MACHINE FOR DISTRIBUTING INSECTICIDES.

SPECIFICATION forming part of Letters Patent No. 555,256, dated February25, 1896.

Application led February 16, 1895. Serial No. 538,718. (No model.)

To all whom it may concern.'

Be it known that I, VILLIAM R. MONROE, a citizen of the United States,residing in Unionville, in the county of Lake, State of Ollio, haveinvented a certain new and useful Machine for Spreading Insecticide andInsectifuge Powders, of which Vthe following, with the accompanyingdrauings, is a speciiication.

The object of my invention is a machine that is simple in constructionand durable in use, and that is adapted to automatically spread orscatter evenly insect-expelling, insect exterminating, and fungidestroying powders over trees, Vines, shrubs, plants, flowers, dac., andto distribute other material over a field, and to prode a constructionof machine having a narrow tread to travel between rows of grape vines,dsc., with the weight so disposed that it will not tip over when uponrough ground.

My invention consists in the novel features of construction and in thecombination of parts described herein and defined in the claims.

In the drawings, Figure 1 is a side elevation, a part of the truck-frameand the ends of the thills being broken away. Fig. 2 is a plan of themachine, partially in horizontal section on the line of the axles of thetractionwheels. Fig. 3 is a rear-end eleva-tion, a part of thetruck-frame being broken away. Fig. 4 is a broken section on the line 44 of Fig. 2. Fig. 5 is a vertical section of one of the spreaders and abroken section of one of the outletpipes.

ln all the figures of the drawings like gures of reference refer to likeparts.

l l are traction-wheels, which are mounted upon the spindles 2 2C Thespindles 2 2 are lateral extensions of the upper ends of the U shapedaxle 3 in the particular embodiment of the invention herein illustratedand described. A rectangular tru ck-f rame 4 is su pported and carriedoutside of the tractionwheels by the outer ends of the spindles 2 2'.The truck-frame 4 is held in position by the U-bolts 5 5', that hookover the ends of the spindles and pass up through the truck-frame. The U-bolts 5 5' are held in place by the nuts 6 G or by other suitablemeans.

7 is a platform hung below the axle-spindles,

upon which platform stands the rotary blower S. The platform 7 restsupon the upper side of the lower end of the axle 3, and is supported atits back end from the truck-frame 4 by the braces-9 9. The front end ofthe platform 7 is secured by the braces 10 10 to strengthen the truck.

11 is a reservoir in which the powder or other material to be scatteredis carried. The reservoir is carried upon the upper ends of the U-aXle3, or is supported by suitable braces 11 or brackets from thetruck-frame 4. The bottom of the reservoir slopes or inclines to theback end of the machine, as illustrated, that the powder or material inthe reservoir will slide downwardly toward the reservoir-outlet'lz.

Upon the platform 7 stands a rotary blower S, through which the powderor other material in the reservoir 11 is exhausted, as hereinafterdescribed. The rotary fan is of the ordinary construction, having aseries of blades or vanes rotating upon a common center inside of acircular casing, the casin g having an exhaust-opening S extendingtherefrom tangentially. As this construction of fan is Very well knownits details of construction are not illustrated in the drawings.

Other forms of exhaust-blowers than that shown may be employed in theembodiment of my invention.' Any suitable air-forcing device will answerthe purpose.

The rotary fan S is driven by suitable multiple gearing from thetraction-wheels l 1. The intermediate drivin g mechanism between thetraction-wheels and the fan, which I have employed in thewithin-described embodiment of my inventiomconsists of thesprocketwheels 13 13', which by suitable means are made to rotate withthe traction-wheels and upon the same axial line; the pinions 14 14',that are loose upon the horizontal shaft 15; the clutch mechanismhereinafter described; the sprocket-wheel 16 fixed upon the horizontalshaft 15, and the pinion 17 lined upon the fan-shaft 1S with theflat-link chains 19, 15) and 20. in boxes 2l 21, fixed upon thetruck-frame 4, and the fan-shaft 1S rotates in the boxes 22 22 at thetop of brackets 23.

Connected with the tangential outlet S of th e blower S is a bifurcateddischarge-pipe 24.

The horizontal shaft 15 rotates ICO At the upper ends of the branches24' 2%" are spreaders 25 25. The lower ends of the spreaders areconnected with the upper ends of the branches 25k 24 of the bifurcateddischarge-pipe by a ball-and-socket joint 25h, as shown by Fig. 5. Theupper side, 25, of the spreaders projects beyond the lower side and isslightly bent, somewhat of the form shown, and forms a lip fordefiecting the powder or material scattered by the machine. The openingsthrough the spreaders are of increasing width and of decreasing heighttoward their outer ends, as illustrated. This form of spreaderdischarge-opening with the projecting lip 25n causes the powder to 'Hyout in a broad thin cloud.

At the back end of the reservoir 11 is a bearing 2G, which carries theshaft 27 of the agitator 28. The agitator is in proximity to thedischarge-openin g 12. The agitator is driven by means of the pulley 29,fixed upon the main horizontal shaft l5, the pulley 30, fixed upon theouter end of the agitator-shaft 27, and the belt 31.

The converging of the back end and one side of the reservoir 11, asillustrated, forms a pocket of the reservoir in which the agitator 28works. This facilitates the passage of the powder in the reservoir tothe dischargeopening 12.

Below the opening 12 there is a passage-way or chute from the reservoirdischarge-opening l2 to the blower. The chute shown in the drawing is apiece of sheet metal bent to a cylindrical form and having an opening onits upper side below the reservoir-opening 12. The outer end of thechute 32 is left open to admit air freely to the blower S. The chute 32,the way through the blower, and the bifurcated pipe 21, with itsbranches 24 24, form a continuous passage from the reservoir 11A to thespreaders 25 25.

I have provided for throwing the machine in and out of gear by theclutches 33 33 34 31'. The clutch part 33', made integral with orconnected with the pinion 14, and the clutch part 3ft', made integralwith or connected with the pinion 1l', are loose upon the shaft 15, andthey are capable of turning thereon. One part 33 of one of the clutchesis fixed to the shaft 15 and the one part 31 of the opposite clutch. isfixed to the sprocketwheel 16, or is formed upon the hub of saidsprocket-wheel, and both said sprocket-wh eel 16 and its accompanyingpart 35i of the adjacent clutch are keyed or otherwise firmly fixed tothe shaft 15. Upon the back end of the truck-frame et are plates 35 35,having in the upper edge thereof notches 3G 3G. Brackets 37 37 aresecured to the back corners of the truck-frame 4f, upon which bracketsare pivoted the clutch-levers 38 3S'. Vhen the parts are in the positionshowni in Fig. 2, with the clutch-levers in the notches 3G 3G', themachine is out of gear. lVhen the clutchlevers 3S 3S are released fromthe engaging notches 3G 36, the springs 3i) 39 throw the movable parts33 3l into engagement with the fixed parts 34 of the clutches and themachine is in gear, so that the fan and the agitator will be driven asthe machine is drawn forward.

Upon the sides of the reservoir l1 are brackets 40 40', carrying idlersAll 11 pivoted thereto, and are adjustable by means of slots l0 andbolts 42 to adjust the tension of the drivechains 19 19.

43 43 are thills to provide for guiding the machine by the horse oranimal drawing it.

In operation, the reservoir is filled or partially filled withinsecticide-powder orinsect ifu ge-powder, or other powdered material,and the reservoir is closed by means of a cover. (Not shown.) Themachine is thrown in gear by releasing the clutch levers 3S 3S from thenotches or catches 36 36'. As the machine is drawn forward in gear, therotary fan is driven at a high speed bythe multiple gearing described,and the agitator 2S, by reason of its screw form and action, keeps thepowder stirred and loose at the reservoiropening 12, so that the powderwill not impact at the lower end of the reservoir, and facilitates thedischarge of the powder to the rotary blower. As powder is exhaustedfrom the reservoir, it passes through the opening 12 and the chute 32 tothe blower, as indicated by the arrows 12 in Figs. 1 and 2. The powderis blown out through the discharge-pipes 2-1 2l" and is caused by thespreaders 25 25 to 'Hy in broad thin clouds, as directed by thespreaders, and to fall upon the vegetation to be treated. As the powderpasses out of the spreaders it strikes against the under curved side ofthe deiiector-lips 25, which causes the powder to be scattered in adesired direction.

The dotted lines in Fig. 2 show the spreaders 25 25 to be adjustableradially and otherwise by means of the ball-and-socket joint 25h, sothat the cloud of powder may be directed to fall upon rows of vines,plants, rbc., of dierent distances apart. By changing the lip 25L todifferent angles by any known means the direction of the powder may bechanged and the thinncss of the cloud regulated.

It will be seen that when the machine is in use in gear, when turning atthe ends of a field and one of the traction-wheels is backing, theclutch upon that side will turn back without driving the blower. rlheclutches engage when the machine is drawn forwardly, and they do notengage when the machine is pushed backwardly.

By the construction and combination of truck, truck-frame, axle, andplatform upon which the blower rests, the traction-wheels are broughtnear together, so that they will travel between rows comparatively neartogether, and the truck-frame with the extended thills serve to preventvines, shrubs, the., from coming into contact with the tractionwheels,and at the same time the strain upon the blower from the 'driving-poweris trans- IOC IIO

mitted below the axle-spindles upon which the traction-wheels revolveand prevent the narrow truck from being overbalanced above the axialline of the traction-wheels.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. ln a machine for spreading insecticidepowders, a U-shaped axle havinglateral eX- tensions for spindles, traction-wheels mounted upon thespindles, a rectangular truckframe outside the traction-wheels, aplatform at the lower bend of the axle, a rotary blower upon theplatform, driving connection between the traction -Wheels and the rotaryblower, a magazine, an agitator within the magazine, a passage from themagazine to the blower, a spreader, and a passage from the blower to thespreader, substantially as described.
